The prevalence of an enlarged ascending thoracic aortic diameter (AAD) diagnosed by 2-dimensional echocardiography compared with 64-slice cardiac computed tomography (MSCT) was investigated in 97 women and 117 men (mean age 65 +/- 12 years). Enlarged AADs were diagnosed in 42 of 214 patients (20%) by echocardiography and in 45 of 214 patients (21%) by MSCT (p = NS). The sensitivity, specificity, positive predictive value, and negative predictive value of echocardiography in diagnosing an enlarged AAD using MSCT were 69%, 93%, 74%, and 92%, respectively. A Bland-Altman plot showed that the agreement for AAD measured by echocardiography and MSCT was 95% inside the 2-SD limits. In conclusion, the sensitivity, specificity, positive predictive value, and negative predictive value of 2-dimensional echocardiography in diagnosing enlarged AAD using MSCT were 69%, 93%, 74%, and 92%, respectively.
在97名女性和117名男性(平均年龄65±12岁)中,研究了二维超声心动图与64层心脏计算机断层扫描(MSCT)诊断升主动脉直径(AAD)增大的患病率。214例患者中,超声心动图诊断出42例(20%)AAD增大,MSCT诊断出45例(21%)(p=无显著差异)。超声心动图在使用MSCT诊断AAD增大时的敏感性、特异性、阳性预测值和阴性预测值分别为69%、93%、74%和92%。Bland-Altman图显示,超声心动图和MSCT测量的AAD在2-SD范围内的一致性为95%。总之,二维超声心动图在使用MSCT诊断AAD增大时的敏感性、特异性、阳性预测值和阴性预测值分别为69%、93%、74%和92%。
